Prabir's PEGY Ratio Calculator

Dividend‑adjusted PEG per Peter Lynch’s growth + yield idea. Professional inputs. Clear outputs.

Inputs

Forward P/E (next‑12‑months EPS) preferred; TTM acceptable if forward is unavailable.
Type your view directly or auto‑fill it from the EPS history panel.
Forward annual dividend yield. If this is 0, PEGY reduces to classic PEG.
PEGY
—
Formula: PEGY = P/E ÷ (EPS growth% + Dividend yield%) • Both inputs in percentage points. If growth + yield ≤ 0, the metric is not meaningful.

Auto‑Fill Growth from EPS History (3–5y)

Enter last 3–5 annual EPS (₹/share), oldest → latest. We compute a robust average growth and write it into the EPS growth % box.
  • All EPS positive: we use CAGR over the period.
  • Any EPS ≤ 0 or a zero present: we use median of YoY % changes, each % as (EPSₜ − EPSₜ₋₁) / |EPSₜ₋₁|, clamped to [−100%, +200%] to reduce outliers.
  • Too few valid pairs: fallback to a linear trend per year scaled by average absolute EPS (also clamped).

Method Summary (read first)

• PEGY is a dividend‑adjusted form of the PEG concept popularised by Peter Lynch: add dividend yield to expected EPS growth, then divide your P/E by that sum. Use as a screening heuristic, not a full valuation.
• Growth Auto‑Fill computes a robust average from 3–5 years of EPS, handling negatives and zeros (CAGR when all positive; otherwise robust median YoY%).
• Keep inputs consistent (forward P/E with forward‑looking growth/yield). If growth ≤ 0, PEG/PEGY is not informative—switch to cash‑flow models.
